content.bodyThe SRU is Alfa Laval's hygienic rotary lobe pump: a positive displacement design for processes where product quality matters as much as throughput. Its low-shear, low-pulsation action moves viscous and shear-sensitive fluids gently, so it fits food, dairy, beverage, home and personal care, biotechnology and pharmaceutical duties. Channel Pumps supplies the SRU and sizes it to your duty point. We match the pump head, connections and configuration to your flow, differential pressure, medium and hygiene requirement.
content.how_it_worksA rotary lobe pump moves fluid by positive displacement. Two high-precision rotors turn in mesh inside the pump head, carrying fluid around the casing from inlet to outlet in a gentle, low-pulsation action. Because the fluid isn't forced through a tight clearance at speed, shear stays low. That is what protects delicate products. The SRU adds a front cover seal with defined compression, a rotor nut retention design, and a drainable pump head to support cleaning. It is built to 3-A Sanitary and FDA hygienic standards, and is available to ATEX requirements for explosive atmospheres.
